Description

Technical Field

[0001] The utility model belongs to the technical field of steam generating devices, and in particular relates to an industrial steam generating device. Background Art

[0002] A steam generator (boiler) is a device that converts water into steam and is widely used in many fields. Its main working principle is to provide heat through a heating source to gradually increase the temperature of the water. When the saturation temperature is reached, the water begins to convert into water vapor. The actual operation of the steam generator is very convenient. No special person is required to be on duty. One-click operation can be achieved through the Internet intelligent control. The application scenarios of steam generators are very wide, covering industrial production, food processing, heating and heat supply, medical and health care and other fields. In industrial production: steam generators provide steam in chemical, pharmaceutical, textile, printing and dyeing and other industries.

[0003] There are many disadvantages in the use of steam boilers. Water tube steam boilers need to be opened and closed frequently, which not only increases the operating cost, but also may cause additional wear and tear on the equipment. The thermal efficiency of traditional coal-fired boilers is low, and the energy in the fuel cannot be fully utilized, resulting in energy waste. The main reasons for the unstable output steam pressure of the boiler are: problems with the water supply system: unstable liquid level will cause large fluctuations in boiler pressure. Changes in external loads, such as increases or decreases in steam consumption, will cause the boiler to not have time to adjust to the new operating conditions, thereby causing changes in steam pressure. Fuel supply problems: If the fuel supply is insufficient or the oil pump fails, the boiler pressure will also be unstable. Combustion efficiency problems: If the combustion is incomplete, it will affect the thermal efficiency of the boiler, which will lead to unstable pressure. Utility Model Content

That is, each steam generating module can be controlled by a valve.

DETAILED DESCRIPTION

[0047] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0048] like Figure 1-17 As shown, an industrial steam generating device includes a frame 1, a water tank 2, an oil tank 3 and a steam generating module 4, wherein the water tank 2, the oil tank 3 and the steam generating module 4 are all fixed on the frame 1; a flue gas main pipe 5, a water main pipe 6, an oil main pipe 7 and a steam main pipe 8 are fixedly connected to the frame 1; the water main pipe 6 is connected to the water tank 2, and the oil main pipe 7 is connected to the oil tank 3.

[0050] The steam generation module 4 includes a shell 45, a burner 41 and a heat exchanger 42. The heat exchanger 42 is arranged in the shell 45, and the burner 41 is fixedly connected to the shell 45. The bottom of the shell 45 is provided with an air inlet 450, and the top thereof is provided with a smoke outlet 451.

[0051] There are several steam generating modules 4, and the steam ports 44 in each steam generating module 4 are connected to the steam main pipe 8 through a steam branch pipe. The steam branch pipe is provided with a valve, and the steam generated by each steam generating module 4 can be discharged into the steam main pipe 8 through the steam branch pipe. That is, each steam generating module 4 can be controlled by a valve, and when the steam pressure generated by the corresponding steam generating module 4 reaches the requirement, its valve is opened; otherwise, it is closed. Therefore, by controlling each steam module 4 separately and each steam module 4 working separately, it can be ensured that the steam pressure entering the steam main pipe 8 is stable and meets the use requirements. Moreover, when the required amount of steam is reduced, some steam generating modules 4 can be closed to reduce energy waste.

[0052] The water inlet 43 in each steam generating module 4 is connected to the water main pipe 6; specifically, a water pump is provided in the water tank 2, and water is pumped into each steam generating module 4 through the water pump. The smoke outlet 451 in each steam generating module 4 is connected to the smoke main pipe 5, and an exhaust fan is provided on the smoke main pipe 5 to extract the smoke. The oil tank 3 provides fuel to the burner 41 in each steam generating module 4 through the oil main pipe 7. Specifically, a corresponding oil pump is provided in the oil tank 3.

[0053] An air inlet 450 is provided at the bottom of the housing 45 for supplying air to the burner 41 ; a smoke outlet 451 is provided at the top thereof, through which smoke inside the housing 45 can be discharged.

[0054] Specifically, the heat exchanger 42 includes an outer tube group and an upper tube group 423. The outer tube group is in an "n" shape, and is composed of a left tube group 420, a right tube group 421, and a rear tube group 422. The left tube group 420 and the right tube group 421 are connected through the rear tube group 422 to form an "n"-shaped outer tube group. The left tube group 420, the right tube group 421, and the rear tube group 422 can form a left, right, and rear enclosure.

[0055] The upper tube group 423 is located inside the outer tube group and is connected to the left tube group 420 and the right tube group 421 , that is, it can form an upper, left, right and rear surround to fully absorb the heat of the flame.

[0056] The burner 41 is located at the front end opening of the outer tube group. The burner 41 sprays flames inward through the front end of the outer tube group. The flames can contact the outer tube group and the upper tube group 423, thereby heating the water in the outer tube group and the upper tube group 423 to generate steam.

[0057] Specifically, a water inlet 43 and a steam outlet 44 are provided on the heat exchanger 42 , and water enters the heat exchanger 42 through the water inlet 43 ; and steam generated after heating is discharged through the steam outlet 44 .

[0058] Further, the left pipe group 420 and the right pipe group 421 have the same structure, both including an upper transverse pipe 4200 and a lower transverse pipe 4201, and the upper transverse pipe 4200 and the lower transverse pipe 4201 are connected through a plurality of vertical pipes 4202. The steam port 44 is arranged on the upper transverse pipe 4200 in the left pipe group 420 and / or the right pipe group 421, and the water inlet 43 is arranged on the lower transverse pipe 4201 in the left pipe group 420 and / or the right pipe group 421; that is, one or two steam ports 44 and water inlets 43 may be arranged, which are arranged according to actual conditions.

[0059] Water enters the lower horizontal pipe 4201 and the vertical pipe 4202 through the water inlet 43; the upper horizontal pipe 4200 is a steam pipe, and the generated steam flows into the steam pipe and is discharged through the steam port 44; the water in the steam flows into the vertical pipe 4202 and the lower horizontal pipe 4201 under the action of gravity.

[0060] Furthermore, the inner diameters of the upper transverse tube 4200 and the lower transverse tube 4201 are the same, and the inner diameter of the vertical tube 4202 is smaller than the inner diameter of the upper transverse tube 4200. The setting of the tube diameters can ensure that the water in the steam can gather at the bottom of the upper transverse tube 4200 and flow into the vertical tube 4202.

[0061] Furthermore, the rear pipe group 422 includes an upper connecting pipe 4220 and a lower connecting pipe 4221, and the upper connecting pipe 4220 and the lower connecting pipe 4221 are connected by a plurality of vertical connecting pipes 4222, and the two ends of the upper connecting pipe 4220 are respectively connected to the upper transverse pipe 4200 in the left pipe group 420 and the right pipe group 421, and the two ends of the lower connecting pipe 4221 are respectively connected to the lower transverse pipe 4201 in the left pipe group 420 and the right pipe group 421.

[0062] Since both ends of the lower connecting pipe 4221 are connected to the lower horizontal pipe 4201 in the left and right pipe groups 420 and 421, respectively, water flows into the lower connecting pipe 4221 and each vertical connecting pipe 4222 through the lower horizontal pipe 4201. That is, after water is added, the water level in the vertical connecting pipe 4222 is consistent with the water level in the left and right pipe groups 421. The steam generated in the rear pipe group 422 flows into the upper horizontal pipe 4200 through the upper connecting pipe 4220, and is finally discharged through the steam port 44 of the upper horizontal pipe 4200.

[0063] Furthermore, the inner diameters of the upper connecting pipe 4220 and the lower connecting pipe 4221 are the same, and the inner diameter of the vertical connecting pipe 4222 is larger than the inner diameter of the upper connecting pipe 4220. The setting of the pipe diameter forms a constriction structure at the connection point between the vertical connecting pipe 4222 and the upper connecting pipe 4220, so that the flow cross section is suddenly reduced during the steam flow, and the water droplets contained in the steam or compressed air are separated, thereby further reducing the water content.

[0064] Further, the upper row of tube groups 423 includes a first upper row of tube groups 4230 and a second upper row of tube groups 4231. There are a plurality of first upper row of tube groups 4230 and second upper row of tube groups 4231. The first upper row of tube groups 4230 and the second upper row of tube groups 4231 are arranged side by side with intervals between them; that is, they are arranged in the manner of first upper row of tube groups 4230, second upper row of tube groups 4231, first upper row of tube groups 4230, second upper row of tube groups 4231...

[0065] The first upper tube group 4230 and the second upper tube group 4231 have the same structure, both including an upper steam pipe 424 and a lower heating pipe 425, the steam pipe and the lower heating pipe 425 are connected through a plurality of vertical flue gas heating pipes 426, the lower heating pipe 425 is connected with a circulation pipe 427, and the circulation pipe 427 is inclined. Water flows into the vertical flue gas heating pipe 426 through the lower horizontal pipe 4201, the circulation pipe 427, and the lower heating pipe 425; that is, after water is added, the water levels in the vertical pipe 4202, the vertical connecting pipe 4222, and the vertical flue gas heating pipe 426 are consistent.

[0066] Specifically, in the first upper tube group 4230, the upper steam pipe 424 is connected to the upper transverse pipe 4200 in the left tube group 420; the circulation pipe 427 in the first upper tube group 4230 is connected to the lower transverse pipe 4201 in the right tube group 421. That is, the steam generated in the first tube group is uniformly discharged into the upper transverse pipe 4200 in the left tube group 420 through the steam pipe.

[0067] The overall flow direction is water in the lower horizontal pipe 4201 → circulation pipe 427 → lower heating pipe 425 → vertical flue gas heating pipe 426 → upper steam pipe 424 → upper horizontal pipe 4200 .

[0068] In the second upper tube group 4231: the upper steam pipe 424 is connected to the upper transverse pipe 4200 in the right tube group 421; the circulation pipe 427 in the second upper tube group 4231 is connected to the lower transverse pipe 4201 in the left tube group 420. That is, the steam generated in the second tube group is uniformly discharged into the upper transverse pipe 4200 in the right tube group 421 through the steam pipe.

[0069] The overall flow direction is water in the lower horizontal pipe 4201 → circulation pipe 427 → lower heating pipe 425 → vertical flue gas heating pipe 426 → upper steam pipe 424 → upper horizontal pipe 4200 .

[0070] This structural setting can effectively increase the flow length of the water channel so that it can fully absorb heat; and the steam will not be discharged directly after being generated, but will change its flow direction and converge, thereby discharging the water suspended in the steam. At the same time, the discharged water can flow back to the heat exchanger 42 for continued heating.

[0071] Furthermore, a plurality of spiral grooves 4260 are provided on the outer surface of the vertical flue gas heating pipe 426, and the flue gas can flow along the spiral grooves 4260, thereby increasing the contact area with the flue gas and fully absorbing the heat of the flue gas.

[0072] Furthermore, the inner diameters of the upper steam pipe 424 and the lower heating pipe 425 are the same, and the inner diameter of the vertical flue gas heating pipe 426 is larger than the inner diameter of the upper steam pipe 424. That is, the vertical flue gas heating pipe 426 and the upper steam pipe 424 can also form a constriction structure at the connection point, so that the flow cross section is suddenly reduced during the steam flow, and the water droplets contained in the steam or compressed air are separated, thereby further reducing the water content.

[0073] Furthermore, a drain pipe 428 is connected to the lower horizontal pipe 4201 ; a valve is provided at the drain pipe 428 , and after long-term operation, the valve can be opened to discharge the water in the heat exchanger 42 through the drain pipe 428 .

[0074] Furthermore, the burner 41 is preferably arranged horizontally, and specifically, a methanol burner in the prior art can be used. The following structure is preferably used:

[0075] It includes an air distribution plate 411, an air outlet seat 414, a fire cover 416 and a flame adjustment tube 417.

[0076] An air outlet 415 is provided in the middle of the air outlet seat 414 . The air outlet 415 is composed of a straight section 4150 and a gradually opening section 4151 from the back to the front. The combustible gas can pass through the straight section 4150 and the gradually opening section 4151 in sequence.

[0077] When the fuel in the oil tank 3 needs to be gasified, a gasification device is also provided; for example, when methanol is used as the fuel, a methanol gasification device is provided. The methanol oil in the oil tank 3 is input into the methanol gasification device through the main oil pipe 7, and the methanol is gasified by the methanol gasification device and then input into the gas outlet of the burner in the steam generation module.

[0078] Specifically, the gradually opening section 4151 is in a trumpet shape, which can prevent the fully gasified combustible gas in the combustible gas from remaining in the gas outlet 415 , that is, the combustible gas can flow out through the fire cover 416 along the gradually opening section 4151 .

[0079] The above-mentioned gas outlet seat 414 is connected to the threaded connection through hole of the air distribution plate 411. The gas outlet seat 414 is provided with an external thread, and a corresponding threaded connection through hole is provided in the middle of the air distribution plate 411. A plurality of fire holes are provided on the fire cover 416. The fire cover 416 is fixedly connected to the gas outlet seat 414. The combustible gas is ejected from the fire hole through the gas outlet 415 and ignited by the ignition needle 412. The flame adjustment tube 417 is threadedly connected to the fire cover 416. The extension length of the flame adjustment tube 417 can be adjusted, that is, the range of flame blocking can be changed, thereby changing the size of the flame.

[0080] Furthermore, the shape of the fire cover 416 is preferably a truncated cone.

[0081] Furthermore, a circle of protrusions 4140 is formed on the air outlet seat 414. When the air outlet seat 414 is connected to the air distribution disk 411, the protrusions 4140 can contact the air distribution disk 411 to play a tightening role.

[0082] Furthermore, the flame adjustment tube 417 can only be adjusted when it is not installed in the burner. If the flame adjustment tube 417 is located inside after installation, it cannot be adjusted again. Therefore, an adjustment mechanism 418 is also included, and the adjustment mechanism 418 is connected to the flame adjustment tube 417. The flame adjustment tube 417 can be driven to rotate through the adjustment mechanism 418; and even after installation, it can be adjusted as needed.

[0083] Specifically, the adjustment mechanism 418 includes a gear ring 4180, an adjustment column 4181 and a connecting block 4182. The connecting block 4182 is plugged into the air distribution disk 411, and a corresponding plug-in hole is provided on the air distribution disk 411. The gear ring 4180 is fixedly connected to the flame adjustment tube 417, the adjustment column 4181 is threadedly connected to the connecting block 4182, one end of the adjustment column 4181 is fixedly provided with a gear 4183 meshed with the gear ring 4180, and the other end of the adjustment column 4181 is fixedly provided with a knob 4184. That is, after installation, the gear 4183 and one end of the adjustment column 4181 are both located inside, while the knob 4184 and the other end of the adjustment column 4181 are located outside. Therefore, after installation, the adjustment column 4181 is driven to rotate by turning the knob 4184, so that the gear 4183 rotates and meshes with the gear ring 4180, thereby driving the flame adjustment tube 417 to rotate accordingly, thereby changing its extended length.

[0084] Furthermore, a connecting plate 4185 is fixed on the connecting block 4182. When the connecting block 4182 is plugged into the air distribution disk 411, the connecting plate 4185 is fixedly connected to the air distribution disk 411 by bolts, thereby preventing the connecting block 4182 from falling off.

[0085] Furthermore, a notch 4141 connected to the connecting block 4182 is provided on the air outlet seat 414. After the air outlet seat 414 is connected to the air distribution disk 411, the notch 4141 is aligned with the plug hole on the air distribution disk 411, and then the connecting block 4182 is installed and inserted into the plug hole and the notch 4141. That is, the connecting block 4182 can also play the role of a limit pin to prevent the air outlet seat 414 from rotating at will and causing it to loosen.

[0086] Furthermore, the adjustment mechanism 418 further includes a windshield 4186, which is slidably connected to the air distribution plate 411 and is located on one side of the air distribution hole 4110; that is, the windshield 4186 can block the air distribution hole 4110. Specifically: the air distribution plate 411 is provided with a guide column, and the windshield 4186 is provided with a corresponding through hole, and the sliding connection is achieved through the cooperation between the through hole and the guide column.

[0087] The windshield 4186 is fixedly connected with a support plate 4187, which is attracted to the knob 4184 through a magnet; of course, the support plate 4187 can also be rotatably connected to the knob 4184. The support plate 4187 cannot move axially relative to the knob 4184, and can only be driven to move up and down by rotation. The magnet or rotatable connection is selected according to the actual situation.

[0088] By turning the knob 4184, the adjusting column 4181 is driven to rotate, so that the gear 4183 rotates and meshes with the gear ring 4180, thereby driving the flame adjusting cylinder 417 to rotate accordingly and change its extension length. Since the adjusting column 4181 and the connecting block 4182 are threadedly connected, when the adjusting column 4181 rotates, it will move up and down, and the support plate 4187 will also move up and down accordingly through the magnet adsorption or rotation connection. The movement of the support plate 4187 can change the distance between it and the air distribution hole 4110. If the distance is short, the air distribution hole 4110 can be blocked, hindering the air from entering, and vice versa, the obstruction can be reduced.

[0089] At the same time, the thread rotation direction of the adjustment column 4181 is the same as that of the flame adjustment tube 417. That is, when the adjustment column 4181 is rotated clockwise, the adjustment column 4181 moves up, and the gear 4183 meshes with the gear ring 4180 to drive the gear ring 4180 and the flame adjustment tube 417 to rotate counterclockwise, and the flame adjustment tube 417 moves down.

[0090] When the adjusting column 4181 is rotated counterclockwise, the adjusting column 4181 moves downward, and the gear 4183 meshes with the gear ring 4180 to drive the gear ring 4180 and the flame adjusting tube 417 to rotate clockwise, and the flame adjusting tube 417 moves upward.

[0091] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments.
